Question

a car travels 60km in 1hr. 30min.How long will it take to cover a distance of 100km at the same speed? solve by direct and inverse variation​

Answer 1

Step-by-step explanation:

car travels 60km in 90 minutes

thus it travels 60km in 1.5 hrs

thus its speed is 60/1.5 =40km/h

now

to travel 40km it takes 1hrs

then to travel 100 km it takes

100/40=2.5 hrs

so if i am not wrong

2.5 hrs is your answer

Answer 2
